DIRECT AND MESNEASSIGNMENTS, TO THE STANDARD REGISTER COMPANY MANIFOLDI NG REGISTER Application filed April 18, 1925. Serial No. 24,193.

Our invention relates to manifolding machines, and more particularly to manifolding registers, which are operated by a small motor.

In providing for electrical operation of manifolding registers, of the type in which the paper feed is calculated to issue predetermined form lengths of paper, at each cycle of operations, there are a number of features to be arranged for. The paper feed must have a definite cycle with a latch of some character which releases it for single complete revolutions, and then latches it again. The

' motor must have a switch, and there must be mechanism such that when the paper feed is positively stopped, the motor must be permit ted to revolve a little further and the driving electric circuit must be broken.

In our United States Patent No. 1,437,949, dated December 5th, 1922, we have shown a mechanism which provides for the features outlined in connection with a particular type of motor which shuts itself off when'subj ected to excessive load, and in which the drive to the paper feed includes a friction which applies the excess load to the motor, when the paper feed is stopped.

The present invention relates to improvements in the mechanism shown in thexpatent referred to.

Our object in the present construction is to provide for a motor driven operating device for manifolding machines which is a unit of itself, which can be mounted on a machine in place of theregular operating handle, and

the machine converted into an electrical type without other change.

Our object is to simplify the friction device of the former construction and embody all of the driving features in a very compact frame, carrying stops; switches and the like, thereby providing a complete driving unit.

Our object is to provide in addition to the structure of the motor we formerly used, an automatic switch cut-out which gives a starting impulse to the automatic shut of! features of our former construction. This cut-off would enable us to do away with the automatic friction cut-oil should this be desirable,

reduction train,

and provides against the failure of the friction cLlt-ofl", in case the driving friction to the feed shaft connection should become too loose to result in the automatic action.

Our object further is to provide for the paper feed release, now located on the motor drive unit, being so located'as to result in the operator moving the paper feed release when he operates the switch. It is to our minds undesirable to have the switch and the paper feed release element all part of one lever train, and connected operatively to each other, as

. this requires braking devices and a complicated structure by means of whichto avoid the placing of excessive load on the motor before it starts its operation, and prevents releasing the paper feed, or releasing the motor as a selective particular operation, should anything get out of shape in the operation of the machine.

These several objects we accomplish by that certain construction and arrangement of parts to be hereinafter more specifically pointed out and claimed.

Referring briefly to the motor, we primarily refer to our Letters Patent heretofore referred to. The case of the motor is formed as a housing 1 for the rotor and field 2 and 3, and the commutator 4. The rotor shaft 5 extends upwardly through a portion 6 of the casing, which portion 6 is'expanded at 7 to house the driving worm gear. The rotor shaft 5 is formed with threads, of a worm type, at 8. The switch is mounted on the top of the portion 6 of the housing, in an added box 9. It is formed with contacts 10, which are connected together by the fins 11 on the plunger 12. The fins are given a positive make and break by a coiled spring set around the plunger in a manner that is familiar in switch practice. The plunger is mounted in a spring depressed housing 13 that slides in the upper portion of the casing part 6, and this housing engages the upper end of the rotor shaft.

When the rotor shaft is not permitted to revolve because of stoppage of the worm wheel that it engages and drives, the action will be to feed the rotor shaft and rotor upwardly, the shaft acting as a screw, which in turn presses up on the housing of the switch plunger, and throws open the switch.

Referring to Figure 7 it will be noted that the worm wheel 14 is provided with a spindle 15, which engages in a bearing formed in the boss 7 a of the housing portion 7, of the motor frame. This worm wheel meshes with the worm, when in place, and carries on its face a conical disk 16.

The drive connection for the feed shaft of the manifolding machine is formed as a friction cone 17 mounted on a spindle 18, which passes throu h the spindle 15, and pro- ]ects with a threa ed end 19 at the outside portion of the frame part 7. A spring 20 is set over the portion 19, and nuts 21, mounted on the threads thereof, thereby compress the spring and draw the friction cone into the friction disk, providing a friction drive for the spindle 18.

On the outer portion of the cone is mounted a cam 22, having a nose 23, which serves together with a lever to be described, as a paper feed stop. This cam has also a stud 24 thereon WhlCh cooperates with a pawl and slide bar, to give an upward impetus to the switch plunger of the motor, serving to throw off the motor as the feed comes to a stop.

The spindle 18 has in addition to the frictioncone cam and stud, a fitting for engagement with the end of the feed shaft of the manifolding machine. The shaft is indicated at 25, and has a slot in the end terminating in a rounded portion 26. There is also a pin 27 in the shaft, which acts as a key for the usual operating handle. It will be understood that this is'merely one particular kind of a connection for the operating handle of a feed shaft in manifolding registers, the point being that the spindle of the friction cone has a device similar to the handle, which would naturally be modified ,to suit the type of machine upon which the motor unit was to be mounted. In this instance the friction cone spindle is fitted with a collar 28, which is shaped to fit over the end of the feed shaft and is notched out to engage over the pin 27. A cotter pin or other form of pin is inserted through theholes 29 in the collar and throughthe rounded portion 26 of the slot in the end of the feed shaft.

Thus in the particular example shown, the connection of the friction spindle is a mere matter of replacement for the usual manual feed handle on the feed shaft.

The motor itself has a strap 30 secured thereto, which is bolted as at 31 to the side of' the manifolding machine, indicated at 32.

The stop levers and'controls are mounted on the motor casing, against the housing porarrange within the housing portion 7, a conical shaped strip of thin metal 34, engaging the seat 34, and wiping the rear face of the concave plate, that is part of the worm wheel.

Referring to the common features of the two devices, (Fig. 8) there is a lever 35 mounted over a stud 36, said lever having an elongated slot arranged over said stud, and the stud being located on an extended portion from the plate 33.

' A spring 37 tends to pull this lever upwardly. he lever has a hooked end 35" which lies under influence of the spring against the cam 22. The nose on the cam engages the end of the lever at the end-of each single revolution of the friction cone spindle, and is thus brought to a positive stop.

The sliding bar 38 is provided, and held on a stud 39, which engages a slot in the bar. The bar is held up by a spring. On the bar is a pawl 40 which is engaged by a spring 41 to hold it normally against an car 42 of the bar. The pawl can swing in the other direction from the ear against spring tension.

A projection 35 on the top edge of the the pawl will swing against its spring, awayfrom the projection on the lever, so as to permit the lever to move up under influence of the spring'37, far enough to engage the cam again.

In the preferred form of device, the bar 38 is provided at its upper end with a turned over portion 38 which has a hole in it, sufficient to clear the button 43 on the top of the switch plunger. sitioned just above the said button, with the button lying partially in the hole, in our preferred structure.- or tongue 44, which has a hole to freely clear, but to be guided upon the switch plunger. The tongue 44 will be far enough down on the plunger to prevent the head from oper-' ating the lever in the operation of depression sufficient to throw the switch.

Also mounted on the plunger rod, and in this instance fast on the plunger, is another bar 45, which extendsdown into proximity with the cam on the friction cone spindle,

and is there projected across the top of the cam at 45 The stud on the cam is set to the switch plunger an upward thrust sufficient in most'instancesto throw the switch entirely out. If the operator leaves his hand on the switch button and the top of the bar 38, this kick-off device will warn him to let go.

In the second form the kick-off device is in the form of a pawl 50 which is positioned to be struck up by the stud 24 on the cam, but in this instance engages a stud 50 extending inwardly from the bar 38. The bar 38 is provided with the tongue 51 which in this instance engages over the switch plunger as does the tongue 44, but is fast on the rod, or so near the top as tobe operated by the button of the plunger when depressed. The depression of theswitch plunger will operate the sliding bar to release the paper feed be: fore the switch is thrown to close the circuit to the motor, and the stud on the cam throws up the bar 38 so as to push the plunger head upwardly and release the switch at the moment that the paper feed is positively stopped.

It will be evident without description of the mode of operation of the register, that a single manual operation will pick up both the paper feed latch, and start the motor. The entire driving mechanism is in the mo- The hole will be po- It will also have a lip tor and is removable or mountable'as such in place of a manual operating handle. The various features of advantage in this type of feed for manifolding machines are covered in our patent heretofore referred .to, to which reference is made.

Referring to the usual manifolding register, in which a feed shaft 25 (Fig. 7) engages the paper to be fed, the'operator will depress the motor switch plunger and the accompanying bars, which will result firstly in a release of the latch mechanism and then secondly in an energizing of the motor, through closure of the switch. The motor drive will then rotate the feed shaft one complete revolution, thus feeding a measured quantity of paper. As the close of the revolution approaches, the 'kick-ofi device will throw up the motor switch plunger which stays down due to the snap switch structure described, until forced upwardlyby auto maticaction of the motor, which action is thus accelerated by the kick-off, Immediately following the kick-off, the cam nose will come against the latch and the paper feed shaft will be stopped, completing a feed cycle.

Having thus described our invention, what we claim as new and desire to secure by-Letters Patent, is 2- 1. In combination with a manifolding machine having a feed shaft for operating a paper feed, an electric mechanism comprising in one structure switch controlled circuitconnections, a driven member for said shaft, and a positive stop, means for opening the switch automatically upon positive stopping,
